Question

derive the area of parallelogram analytically and verify the same.​

Answer 1

This page describes how to derive the formula for the area of a parallelogram. It works by moving a piece of the parallelogram so as to make a rectangle with the same area, which is easier to calculate.

Start with a parallelogram with known base length (width) w and altitude h (height).

Cut off a triangular section.

Translate (move) the copy to touch the original so as to create a rectangle.
